Model 3D

This is what i do for my project, which is 3D model, and i decided to do topic solid geometry.
Although you may think that it was easy to do that but it actually need a lot of effort and time! You can try to do it on your own, what you have to prepare is only A4 paper, sciscor, glue, ruler and also pensel. See, the material is all very easy to gain and it really worthy to have a try on it!
I feel really satisfied after doing all this, have a feeling like back to secondary school sumemore xD
Now, have a look on what i have done^^

All of the 3D model that i have done^^

This is pyramid, i feel most satisfy with this!

This is cone, this one quite hard to do because of the round surface area below is hard to attach to the upper surface of the cone.

This is rectangle

This one is cylinder, and is the model that i take the longest time to finsh it!

This is cube, small cube, have a big one some more

This is triangular prism, a bit looks like a pyramid

And this is the big cube! i want to keep all my 3D model inside this big cube ^^

 Hope you enjoy with what i have done ;)

Form 1 Chapter 7 >>> Heat

This is the last topic for Form 1 Science syllabus, hope you all enjoy all the content i post here ^^

Heat is the amount of energy contained in a substance. Its SI unit is Joule (J).

Temperature is the measurement of the degree of hotness or coldness of a particular object. Temperature can be measured by a thermometer and is measured in degree Celcius.

Heat and Temperature

Conduction is the process of heat tranfer from a hot area to cold area throughout a solid.

Different solid conduct heat at different rates.

Substances which allow heat to flow quickly are called conductors while allow heat to flow slowly are called insulators.

Electrical Conductor

Electrical Insulator

Convection is the process of heat transfer in fluids as a result of the movement of the fluid from a hot area to a cooler area.

Radiation is the process of transfer of heat from a heat source to the surrounding without the presence of any medium.

Conduction, Convection, and Radiation

Medium is a transmitting substance which allows heat to be transferred. For example, particles of solids and liquids.

The principle of heat transfer in everyday life can be through using kitchen utensils for cooking, air-conditioners, electric kettle, refrigerators and others.

The principle of heat transfer in nature can be seen in sea breezes, land breezes and the warming of the Earth by the Sun.

Land Breeza

Opaque and dull surfaces absorb and radiate heat more effectively than shiny surfaces.

Book Cover

This is first time i design a book cover for my project work! Initially i thought it was easy but absolutely it was not! I keep design and design and i get one quite satisfy and after i print out, it was a wrong thing totaly from my design because i was using a wrong landscape.
However, luckily i able to finish my book cover design before presentation and i hope other also will feel it like a real book cover as i really put a lots of effort and time especially in design! Hope that others will like it too! haha^^

This is the front page of my book cover ^^

And this is the back cover of the book 

hehe finally it look like this! xDD

This was really a good experience to me, now i am very proud to say i had already success to design a book cover haha! xDD

Form 1 Chapter 6 >>> Sources of Energy

Here is some important part in Chapter 6, students can have a review here^^
6.1   The Various Form and Sources of Energy

- Energy is defined as the ability to do work. Energy is measured in joules (j).

- Energy can be found in many forms :

a) Kinetic Energy

• Kinetic energy is the energy possessed by a moving object.
• The kinetuc energy of an object depends on ots mass and velocity.

example of kinetic energy-running of leopard

b) Potential Energy

• Potential energy is the energy stored in a body due to its position (gravitational potential energy) or its physical condition (elastic potential energy).
• The gravitational potential energy of an object depends on : the mass of the object, the distance of the object from the Earth's surface, and the power of the gravitational pull on the object.
• A falling object gain kinetic energy but loses potential energy.
• Elastic potential energy exists in only elastic substances such as spring or a rubber.

elastic potential energy

c) Heat Energy

• Heat energy is the energy that is stored in hot object.
• The heat energy of a body depends on its temperature and volume.

Heat Energy

d) Light Energy

• Light energy is the energy produced by an object that emits light.
• Light energy can travel in a vacuum and in a straight line in the form of waves.

example of light energy

e) Sound Energy

• Sound energy is the energy produced by a vibrating object.
• The vibrating air forms sound waves.

example of sound energy-drum

f) Chemical energy

• Chemical energy is the energy stored in a chemical substance.
• When substance undergoes chemical reaction, chemical energy which is stored will be released and converted into other form of energy.

example of electrical energy-battery

g) Electrical Energy

• Electrical energy is the energy produced by the flow of electric charges

example of electrical energy

h) Nuclear Energy

• Nuclear energy is the energy stored in the nucleus of an atom.
• Also known as atomic energy.

example of neclear energy-nuclear plant

i) Mechanical Energy

• Mechanical energy is produced when a machine or object change its position.

example of mechanical energy-used in meter glass

j) Solar Energy

• Solar energy is produced during the process of nuclear fusion in the Sun's core.
• Almost all the energy currently available comes from the Sun.

Solar energy comes from Sun

Sources of Energy
Types of energy source on Earth

• Fossil fuels
• Biomass fuel
• Radioactive substance
• Mechanical sources
• Geothermal sources
• Sun

6.2   Renewable and Non-Renewable Energy Source

• Renewable energy source of energy are energy sources which can be used again because the supplies are not limited. Example : wind, solar, hydro, wave, biomass, etc.
• Non-renewable energy sources of energy are sources of energy which are limited in supply and will be used up in a short period of time. Example : fossil fuels and radioactive souurces.
